Thank you so very much for all this extensive help!

I was looking for W123... Guess need to be more open minded!

Well, according to gsxr the diaphragms are no longer available. I don't have time to pull the pod, manufacture a diaphragm, and then hope it works. Now if I had a spare to look at, I might think differently.

Though now that I think about it, tomorrow is Thursday. That mean I wouldn't get parts until next Friday. Maybe I should set aside Saturday and go down to the yard and see if I can find a replacement pod?

How long do you think it last? Is it worth it?
